I've always heard the 5 lb. for every inch after 5 ft. guideline too. However, I know that your frame size does matter there too. That's the guideline for someone who has a medium sized frame, but it increases by 10% for those with a large frame, and it decreases by 10% for those with a small frame. I have a small frame and at 5'6 I should weight 117 (which is how much I weigh now). I do not in any way look too skinny or unhealthy. Of course, this is kind of a general guideline just like the
BMI is a general guideline. The only way to really know how much you should weigh is to get your
body fat percentage.
